Imaging system for vehicle

An imaging system for a vehicle includes a rear backup camera and a video display screen for displaying video images derived from image data captured by the rear backup camera. The imaging system generates a backup overlay and an alignment overlay that are electronically superimposed on the displayed video images to assist a driver of the vehicle when executing a backup maneuver. The backup overlay includes a pair of side overlays superimposed on the displayed video images and the alignment overlay is superimposed on the displayed video images between the side overlays. The video display screen displays the video images and the backup overlay is generated responsive to the vehicle being shifted into reverse gear. The alignment overlay is generated responsive to a user input.
